Manufactured from 2010 to 2014
Compact, rational, refined, rigorous / An amplifier so authentically Nagra
For more than half a century, Nagra has designed and built electronics that are un-paralleled else-where. An innovative engineering approach, strict development procedures, manufacturing quality and traditional Swiss finishing: Each Nagra unit represents a new step in audio history.
The Nagra MSA amplifier reflects the Nagra spirit down to the finest detail. Firstly, its aspect: Its compact form finished in beautifully brushed aluminium, the layout of the front panel controls and the modulometer are all typical characteristics of the brand. An indication of a design that is not driven by fashion but by traditions of excellence. A design resulting of the Nagra engineers’ desire to make a concise, ergonomic and timeless piece of electronic, giving to the user as much pleasure years on as the first day.
From an electronic standpoint, the Nagra MSA amplifier adopts a very original approach. It incorporates technology allowing it to go to the limits, in terms of pure audio reproduction, available today. In terms of musicality, transparency, and neutrality, the MSA behaves itself in a very refined manner.
The MSA owes the success of its behaviour, to the control the company has over elegant electronic architecture design. That is to say, highly evolved yet, devoid of artefacts to better concentrate on the operational precision of the unit. The goal is to produce a signal, perfectly amplified in its entirety, on the outputs, without any alteration of its integrity throughout the signal path. This opens the door to reproduction with the highest possible realism, thanks to incomparable know-how.
